Effects of 2-years exposure to (sub-micron) ammonium sulfate particles on growth and gas exchange rates of Fagus crenata (ブナ), Castanopsis sieboldii (スダジイ), Larix kaempferi (唐松) and Cryptomeria japonica (スギ) seedlings

•No significant effect of the particles on growth was observed after 2 years.
•Net photosynthetic rates of 3 species were not significantly changed.
•Net photosynthesis of Cryptomeria japonica was relatively sensitive to (NH4)2SO4.
•Both increase and reduction in net photosynthetic rate were observed in C. japonica.

4種類の植物のうち、スギの光合成速度は硫酸アンモニアの散布に影響を受けていることを見出した。

Four Japanese forest tree species were exposed to submicrometer (NH4)2SO4 particles.
